Warriors should use rogue BoA leathers, satchel loot of the soldier, a seal, sword and board, simple pearl ring and mail BoEs in the rest of their slots.
Shamans deck themselves out in SP gear, find a balance between sp, hp and mana that suits you and the role you wish to fill; more mana for healing, more sp for dmg. Spidersilk drape, 5 hit on boots and lavishly jeweled ring are pretty mandatory, shaman BoAs along with BoA SP maces, the rest are just caster loot; goldflecked, spidersilk boots, WSG ring, smelting pants or 5/5 eagle/DWB to taste etc. The shaman should also use the WSG neck.
The only spec worth considering as a shaman is 3 in ancestral knowledge, 2 in EB radius, 2 in imp GW and 3 in imp healing wave.
Warrior specs are more varied but every1 likes attt amirite?
Edit: oh no BoAs, well then a warrior either needs to use hit pots or simple pearl ring+spidersilk drape+deviate scale belt with rough bronze shoulders and BDA in place of the BoAs.
Shamans can use Talbar or reinforced woolen instead of BoA shoulders and TBJ or inferno instead of chest. I'd advise using either buzzer blade or smites reaver as your SP wep, if you use smites then you can use a different ring instead of lavishly.
